Another try at Cygnus

[DaveS]

Well, I had another go with my old Jupiter-9 85mm, stopped down to f/4. As before, EOS 5D @ iso 1600

Took 24 x 4 sec subs (Of which 21 were used) through a B&W Redhancer filter to cut down LP, then cut the red channel in DSS (Hence the slight cyan tinge).

Visually I couldn't see much below mag 3, but the star-test was my main objective.

Not sure if you'll be able to see it on such a small JPEG, but there is still a fair bit of coma, esp in the corners, it may be ok on a crop sensor.
